摘要: The transcription factor NF-ATc that controls gene expression in T lymphocytes and embryonic cardiac cells is expressed three prominent isoforms. This due to alternative splice/polyadenylation events lead the predominant synthesis of two long isoforms naive a shorter isoform effector cells. Whereas previously described NF-ATc/A contains relatively short C terminus, longer isoforms, B C, span extra C-terminal peptides 128 246 aa, respectively. We show here addition strong N-terminal trans-activation domain, TAD-A, which common all NF-ATc/C second TAD-B, its peptide. Various stimuli induce activity TAD-A also enhance but, unlike TAD-B remains unphosphorylated by protein from 12-O-tetradecanoyl 12-phorbol 13-acetate-stimulated peptide NF-ATc/B exerts suppressive transcriptional effect. These properties -C might be importance for regulation are predominantly synthesized.
